Abstract : The report describes the second phase of a fire protection study comprising (1) evaluation of self-contained portable extinguishing systems meeting specific criteria for the protection of Air Force Mobility Program structures (Potential alternative protection systems are described, compared, and discussed for the various types of bare-base structures. The discussion includes inert gas systems, low expansion foam systems, high expansion foam systems, dry chemical systems and vaporizing liquid systems); and (2) the development of a 0.64-inch orifice upright prototype sprinkler for Air Force warehouse retrofit applications. The success criteria were based upon penetration, drop size, and distribution data previously generated for a pendent version of a large orifice retrofit sprinkler. Nonfire tests were conducted to monitor changes in the above parameters as design changes were instituted. These tests are described and discussed in detail. A successful large-scale fire test was conducted which verified initial findings. (Author)
